Cosmic Distance Ladder
An excellent thread explaining the cosmic distance ladder with helpful graphics, by PhD candidate Sharan Banagiri: https://threadreaderapp.com/thread/1288230254151073792.html. The original source is from this tweet thread.
Some infographics about the cosmic distance ladder:
[graphic source (credit: Matt Perko) from a UCSB article The Standard Siren] A graphic illustrating the technique of “building up a distance ladder using a number of different techniques for various ranges.”
The three rungs of the distance ladder, from a presentation by Stephen Feeney at the Gravitational Wave Probes of Fundamental Physics (11-13 November 2019) conference. The slides of this talk (keynote file format) are available here.
The graphic below is from page 49 of the paper A 2.4% Determination of the Local Value of the Hubble Constant [arxiv:1604.01424]
